POTS EOL?

I find ATA's a hit and miss also. Then retransmissions start and the client likes to restart from page 1.
Try @Skyetel fax solution.

@JaredBusch any recommended ATA's that you use? I have used the Cisco SPA112 and one of the Grandstreams (can't remember the model number).
I only use the Grandstream ATA line for pots handoff.
Previously the HT700 series and now the HT800 series.
I’ve used others but always come back to these.

Same ones that we use.

I do currently have one ATA in "testing" mode that starts having issue around page 40-45. Anything less seems to have a 90% success rate.
We are about to launch support for HTTPS fax, which should give SkyeFax a nearly 100% delivery success rate. Our ATAs that use T38 are about ~93% successful. That 7% is up to the Fax machine, not us.

The alarm company calls when the signal gets interrupted after a period of time. Just like the would if the fire took out the router/fiber.
I strongly recommend switching your alarm and elevator phones to using SIM Cards. Most alarm companies and elevator companies offer this for a vanishingly small amount of money (like $30/yr or something tiny).

I received an email this morning
anyone else heard of this EOL on copper pair?
Not that I have any - everything I have is Cox - analog over cable.
Yep, Century Link kicked us off in Feb with 30 day's notice. Scrambled to ATT and now paying $80 per line when we were paying $22.
Why did you stick with copper?
Stupid faxes and fire alarm. Like you, we get thousands of pages a month. Also, at the time we found out our fire alarm does not have a wireless option either. UGH. Just a crap show....
Then you have to ask... is it really a fire alarm? What happens when the fire takes out the cable? I'd leave any service like that. For a fire alarm, you need a certain minimum standard and this falls below any reasonable level of acceptance.

None of ours that had POTS was like that. They would call out. This is a direct phone line that is "always on" and talking? That's got to be insanely expensive.

Yeah that seems insane because the line would always be busy using minutes.....

Yeah, Which on an Internet line is easy to do. But a traditional phone line that's a circuit tied up.

Apologies. It wasn't a constant connection but more like a "ping." I don't know the technical details but if the alarm system discovered no dial tone after X seconds/minutes, then try line 2, wait X, if nothing for either, wait one more cycle, if none, set alarm system to beep for a few minutes and check. If still nothing, call client to let them know to fix situation.

As someone that did alarm systems installation professionally, I can answer that easily.
For legacy POTS, an alarm system will have a 4 wire 22 awg cable ran from the POTS demarc to the the alarm system location.
At the demarc, the whatever is connected to the telco handoff posts will be removed. The green/red of the 4 wire will be put in it's place. The yellow/black will then be connected to whatever was removed from the demarc.
At the alarm panel there will be an RJ31X block installed. The RGYB will be terminated to the matching color posts. When nothing is plugged in to the RJ31X, the red and green are bridged back to the yellow and black, thus letting dial tone flow from the demarc to the RJ31X and back to WTFever was previously connected to the demarc. Once the alarm panel telco cable (not a standard RJ11) is connected to the RJ31X that bridge is physically lifted breaking the circuit back to the demarc. At this point relays inside the alarm panel are now the bridge completing the circuit back.
These relays allow the alarm panel to break the circuit to the premise at will. This enables it to disconnect an active call on the wire and then dial out to report what ever event needs reported.
Now on to how it knows if the line is there. This is simply a basic voltage check. When on hook (no active call), voltage on a POTS line is -48V DC. When off hook (on a call), voltage on a POTS line is anywhere from -4V to -9V DC give or take a volt. When ringing in, voltage on a POTS lines is -48V DC and 90V AC @ 20Hz on top of the DC voltage.
So because of all of this, alarm systems simply measure for -48V DC to be present at a fixed interval. If not present, most will also check for the off hook voltage. If that is not there, it will wait a programmed time and then test again. If it fails X number of times (depending on programming or manufacturer design) to detect voltage, it will attempt to seize the line to reset it and test again. If this fails, then you will see a warning on the keypad or control panel about a communications failure.
Additionally, if the voltages are all good, but it fails to dial out and talk to the central office at programmed times, or in the event of an alarm event, it will also show a communications failure. Whether or not that show differently than the no voltage failure depends on the alarm panel.

All of my alarms are installed with a cellular communicator only. My alarm guy says he only wires in telephone in the event there is no cellular coverage (which is non-existent unless extremely rural). I haven't had a telephone cellular communicator in over 5 years.

Customers have alarm systems installed 10+ years ago.

That's all I've been seeing for years, too.

They do, but we always push them to modernize. Security is a place you don't want to let fall apart from lack of maintenance.

Until the phone service changes, there isn’t anything to modernize. A door contact is a door contact. A typical PIR motion sensor is still basically the same. They are tested and working. There is nothing to change.

It's how easy it is to cut. Everyone knows how to defeat security on those old systems. You can have monitors on the line going dead, but those lines go dead a bit too often for that to be really telling.

@jaredbusch Then have them upgrade. Seriously, what in IT lasts 10 years? Its time for a new unit that has cellular connectivity. All the contacts, PIR, etc.. could stay the same obviously as you well know being in the industry.
